Import MySQL database into a MS SQL Server
Use SQL Server Migration Assistant (SSMA)
In addition to MySQL it supports Oracle, Sybase and MS Access.
It appears to be quite smart and capable of handling even nontrivial transfers. It also got some command line interface (in addition to GUI) so theoretically it can be integrated into some batch load process.
This the current download link for MySQL version https://www.microsoft.com/en-us/download/details.aspx?id=54257
The current (June 2016) stable version 6.0.1 crashes with the current (5.3.6) MySQL ODBC driver while transferring data. Everything 64 bit. The 5.3 version with the 5.1.13 ODBC driver works fine.
I suggest you to use mysqldump like so:
mysqldump --compatible=mssql
phpMyAdmin is still a web-app and could potentially have some limitations for large databases (script execution time, allocatable memory and so on).
I found a way for this on the net
It demands a little bit of work, because it has to be done table by table. But anyway, I could copy the tables, data and constraints into a MS SQL database.
